Copper Tablets for Aluminum Alloying

Copper Tablets for Aluminum Alloying are high-efficiency alloying additives specifically designed for aluminum alloy smelting processes. Represented by Cu75 and Cu80 models, they are primarily used to precisely adjust the copper content in aluminum alloys. Each standard tablet weighs 500 grams, with customizable weights available. Added at aluminum melt temperatures of 720–760℃, they melt rapidly and diffuse uniformly, achieving stable control over alloy composition, with elemental recovery rates consistently over 90% and up to 95% under optimized conditions.

[Key Advantages]
· Element recovery rate consistently ≥90% to ≥95%, significantly reducing actual copper raw material consumption costs and preventing batch quality incidents from compositional deviations.
· Operating temperature 720–760℃ closely matches common aluminum alloy smelting processes; no additional furnace temperature adjustments required.
· Standard 500g weight design facilitates weighing and material calculation; custom weights available for more flexible proportioning control.
· Dissolves rapidly in molten aluminum with no significant residue, helping to maintain melt purity and reduce inclusion defects.
· Stable component release and high recovery efficiency significantly improve alloy composition accuracy, reduce rework rates, and optimize production efficiency.

[Product Uses]
· Primarily suitable for the production of various wrought and cast aluminum alloys, playing a crucial role in alloys requiring precise control of copper content (e.g., some copper-containing alloys in 2-series, 6-series, and 7-series).
· Suitable for industrial applications requiring high composition precision: automotive wheels, aerospace structural components, electronic heat sinks, high-strength aluminum alloy profiles, and precision castings.
· Customizable block weights further enhance batching flexibility and fine-tuning capability for workshops requiring small-batch, multi-variety production or frequent alloy ratio adjustments.
· Suitable for correcting copper composition during aluminum alloy recycling, helping recycled aluminum meet target grade standards again.
